Re: [Veritas-bu] Media Tape Writes and Retentions
HI Judy Thank you for your reply Yes I was referring to IMAGES and not actual TAPE but was careless in my general terminology. I have no plans on mixing retentions or leaving a media tape in the Library after it has been assigned. We have some new policies for offsite retentions and I just wanted to throw out a spare of the moment scenario to gather some information. Everything you sent was Extremely helpful and very informative and I thank you for taking to time to explain. There were some things that I did not know that you have cleared up.

If you leave the tape in the library your backups will continue to write to the tape until it is FULL c. If the tape becomes FULL meaning that it has written all the way to the EOT it will NOT write to again until all images on the tape have expired (see #2) d. If you do not allow different retention levels on the same tape - say mixing of 5 week retention and 6 month retention, then it will choose a different tape for the 6 month retention. 4) As the first image is written to the tape it gets an assigned date. On the second day when it writes to the tape it will not change the assigned date, but it will change the expiration date (as the expiration date is based on when the last image on the tape will expire and the tape becomes scratch.) In my production environment we remove the tapes from the library every morning and send them off site. So my assigned time on my tape represents when my backups were done, because I do NOT put more then one days backup on a tape ( what if the tape went bad and I could not read it, I could loose days of data. I do not mix retention periods on my tape because I could have just 1 gig of data on a tape with a 6 month retention and 400 gig of 2 week retention. That tape does not become scratch again until the 6 months have passed.

Re: [Veritas-bu] HP Data Protector Comparisons to Netbackup
Hey Randy Our environment is very similar. For the Main Datacenter we have 1 Master 10 media/SAN Media servers. We currently have around 18 drives in a StorageTek L700. The question I'm having some issues with is that we back up Oracle, SQL DB's, HP-UX, Red hat and Window systems. We have a ton of client servers and I heard that Data Protector doesn't use Policies for all clients (example: Window_File_System policy) but that you must assign each system to it's own backup schedule. I also heard that it doesn't work well with systems outside of HP systems. Is this valid information? Please let me know your thoughts guys.

Guys, Can a catalog recovery fail or cause issues if someone attempts to inventory the robot while the catalog is restoring?

I was running a catalog recovery and one of the datacenter guys decides to try and inventory tapes while it is happening. It seems the first 2 hours the job was moving pretty quickly but since that incident has slown down. This is for a catalog recovery from tape.

All, I have a question I would like to pose because I respect the vast amount of knowledge associated with this forum. We are creating a new backup environment due to some changes and needs. Currently we will be backing up about 40 terabytes of data with a foreseen growth of 30-35% of data annually. Data being backed up includes, Windows File systems, Unix File systems, Exchange, Oracle and SQL. Having a Production site and a DR site using present day Best practices and current available hardware what strategy would you use to set this up? This is even considering purchasing a new library and using LTO4 drives. The backup system will have a dedicated connection. We currently have 8 HP prolient servers as our media servers which may stay. We have some thoughts as to how and what we will do including using vtl's and replication for the catalog but since this forum has so many experienced people I want to get some other professional opinions. If you could set up (from scratch) a Production backup site and DR site based on those data numbers which hardware and strategy would you use considering future growth? thanks -Jackson ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu

Hello Everyone I have an issue where I need to provide a relatively quick DR plan but the issue is a bit difficult to plan a quick and effective solution. We need to provide a solution in case our production Master server goes down and to restore critical data using our DR site across the street. The problem is that the DR site is not a match of the Production site. Production site NB 6.0 Master 6 media servers DR site NB 6.0 Master No media servers The Situation I cannot restore the hot catalog because it is trying to locate those media servers in the database and bombs out. I restored the cold catalog but since we do not delete anything the catalog is huge (198 GB's) Restoring either catalog is going to take hours because of the size and trying to rebuild the catalog everyday doesn't make sense just to restore current data of one of our critical systems. I could use the two phase import but that takes time also and I would like a better solution. Ideas I was thinking of using two options ... the first is: Windows NT NetBackup server: Use the RegEdit application to modify the key HKEY_LOCAL_MACHINE\SOFTWARE\VERITAS\NetBackup\CurrentVersion\Config to add the value FORCE_RESTORE_MEDIA_SERVER and then set the newly added value to fromhost tohost, where fromhost is the media server that performed the original backup and tohost is the desired media host to use for the restore. The 2nd option is the Host Overide Option bpimage.exe -id media_id -newserver hostname -oldserver hostname Only problem is that the DR server is the Exact same name as the Production Master. However I am assuming the main thing is to override the media server that the image is assigned to. Last idea I have is to place a media server in the DR environment matching one of the production media server names. Then only use that media server to back up critical systems so that it will match the DR site media server in the catalog. However this would still involve building the catalog. Any opinions or suggestions would be appreciated !!?? Thanks Jackson ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu

Thanks Jeff ... that was a big help From: Jeff Lightner [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 09, 2008 2:42 PM To: Jackson, Todd; veritas-bu@mailman.eng.auburn.edu Subject: RE: [Veritas-bu] Restore Job hung No work around needed. You basically have to wait for the one stream to finish before the other one starts. It will eventually restore (I've seen it take up to 18 hours because that's how long one stream took to restore then it started the next stream). We've never really worried about it as we usually only see when we're doing a database refresh of one of our test/training instances from our production instance. I'm not sure you really can work around any way. You'd have to try to do individual restores for each stream (backupid) but even then you'd have to make the restores "per tape" which might not be possible if a file spanned tapes within one of the streams as is likely the case. The problem with this is you don't "know" it's the problem until the end of the stream that has the tape. You can "predict" it is by verifying more than one image (stream) uses the same tape but then you have to cross your fingers that this is in fact the issue and not something else. I've seen it frequently enough that once I've done the "prediction" I am willing to let it go and check the next day for completion but then again I have that luxury owing to the nature of the restores. Unfortunately I've never found a way to tell separate streams of the same backup to NOT use the same tape even after asking that question here so its something I've learned to live with on the occasions I've run into it.

Subject: Re: [Veritas-bu] Media Tape lifespan
I stopped using my catalog cold backup tapes when they got over 950
mounts, not because they were failing, but because that seemed quite
high compared to other media in my system. Since I started using the
6.0 hot catalog backup, I'm not using just two pieces of media any more,
so it has managed to spread itself out over about 8 tapes which cycle in
and out of the scratch pool like other media.
For a majority of my 3353 pieces of media, most of them are under 100
mounts after 5 years of use. A few of them are between 100 and 300
mounts, and when I have discovered bad media it is usually during the
very first write process. There have been occasions when restoring from
a questionable tape did not work on the first pass, but was successful
on the second pass. We keep enough backup history on tape to ensure the
one bad media is not the only copy of the file we might need.
I think netbackup increments tape mount every time a tape is inserted in
a drive and the tape header is read. If you check with the drive and
media manufacturers, they count utilization by head passes.
I'd pick a reasonable number, monitor media errors, and make the case
that a $50 tape cartridge is far cheaper than the time and effort
required to recover from bad media, and run the risk that you won't ever
get it back.
-Jon
That may be about right for LTO - I'd have to check the web but
I would say you could have thousands of mounts for an LTO tape. 300+ is
pretty good, and is probably the starting point for a tape to start
getting some good use.
But I am no real expert. Like I said, you could use one tape,
with horrendous problems, and end up chucking it after 10 mounts.
Alternatively, one tape could provide 5000+ mounts, and be
trouble free :-) Many companies may have tapes with double or treble
this figure!
Normally, manufactures of LTO's product a data sheet for life
span of tapes, cycles ect. May be worth looking into.
FYI I have a tape with over 700 mounts - no problems so far.

Also, manufacturer of tape may come into question. As a
